Transesophageal atrial pacing was performed in patients with stable angina pectoris before myocardial revascularization procedure, in immediate postoperative period and in 1 month after complete (n=41) and incomplete (partial) (n=44) surgical revascularization (aorto. coronary bypass graft) or transluminal coronary angioplasty (n=10). initial pacing induced total ST-segment depressions in groups of patients with complete and incomplete surgical revascularization and with transluminal coronary angioplasty were 0.73 +- 0.07 mV, 0.95 +- 0.07 mV, and 0.88 +- 0.07 mV, respectively. After Intervention total ST-segment depressions decreased significantly to 0.01 +- 0.01 mV and 0.12 +- 0.01 mV, to 0.18 +- 0.06 mV and 0.26 +- 0.05 mV, to 0.40 +- 0.13 mV and 0.33 +- 0.09 mV in immediate post procedure period and in 1 year after complete and incomplete revascularization and angioplasty, respectively. Transesophageal atrial pacing is a valuable noninvasive method of evaluation of results of coronary surgery and percutaneous transluminal coronary angioplasty.
